Active Directory for Beginners

How Active Directory Works

You sign in once at work and every computer and shared folder knows who you are; when someone leaves, IT switches them off everywhere at once. That's Active Directory. On a real Windows Server domain in our lab we make an account, see how a computer finds the domain controller through DNS, sign in with Kerberos tickets, watch a new group fail to reach a signed-in user until he signs in again, meet the password policy and Group Policy, and disable an account.
